15931887 ÷ 368 
The aim is to understand the frequency of 368 in 15931887.

Moving on to step 1:
When dividing 1 by 368, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 368

Going ahead to step 2:
When dividing 15 by 368, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 368

Let's proceed to step 3:
368 goes into 159 0 times with a remainder of 159.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 159 after subtracting 0 from 159.
Include the next digit (3) from the dividend after 159, then repeat: 1593 / 368

Going ahead to step 4:
When dividing 1593 by 368, we get 4 with a remainder of 121.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1472 away from 1593, we end up with 121.
Fetch the next digit (1) from the dividend, attach it to 121 and continue: 1211 / 368

Step 5:
1211 divided by 368 is 3 with a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 1104 from 1211, we get 107.
Grab the next digit (8) from the dividend, add it to 107, then carry on: 1078 / 368

Going ahead to step 6:
368 can be fit into 1078 2 times, resulting in a remainder of 342.
Write down 2 as next digit of the result. 
Result so far: 432.0
Deduct 736 from 1078 and we're left with 342.
Fetch the next digit (8) from the dividend, attach it to 342 and continue: 3428 / 368

Let's proceed to step 7:
3428 divided by 368 is 9 with a remainder of 116.
Write down 9 as next digit of the result. 
Result so far: 4329.0
Deduct 3312 from 3428 and we're left with 116.
Take the next digit (7) from the dividend and append it to 116, then repeat: 1167 / 368

Going ahead to step 8:
If we divide 1167 by 368, we get 3 and a remainder of 63.
The next digit of our result is 3. 
Result so far: 43293.0
Deduct 1104 from 1167 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
368 can be fit into 630 1 times, resulting in a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 43293.1
The remainder is 262 after subtracting 368 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 10:
If we divide 2620 by 368, we get 7 and a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 43293.17
Deduct 2576 from 2620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
368 can be fit into 440 1 times, resulting in a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 43293.171
Subtracting 368 from 440 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
If we divide 720 by 368, we get 1 and a remainder of 352.
Use 1 as the next digit of our solution. 
Result so far: 43293.1711
The remainder is 352 after subtracting 368 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 43293.1711 with a remainder of 0.00352.
